but are particularly adaptable forcushioning the closing impact oi' automobile doors and VI! preventing them from rattling, when in the closed position.

The usual practice in the manufacture of automobiles is to provide the doors with buf- Jiers,-which may be either of the adjustable The common form of adjustable butter has a slotted buier block which is secured to the door jambby means of a screw extending thru the slot. In order to compensate for wear, the screw is loosened, the buier block shifted and the screw. tightened to secure the block in place. Thedsadvantage of this arrangement is that the .screw engages a wooden door jamb and after frequent loosening and tightening the threads in the screw hole become worn and the screw cannot be tightened. In the non-adjustable type wear is not compensated for, but instead a new bulier block is installed, when necessary.V Y Y The object of this invention is toprovide a'huer in which the wear will be compen sated for automatically.

It is also an object of this invention to pro.

this vinvention will be apparent from the disclosures in the specification and the accom# panying drawings.

This invention, in a preferred form, isv

illustrated in the drawings vand hereinafter more fully described.

As shown on the drawings: l

In the application' of this invention to automobile doors, it is preferred to mount the buffer in a doorj amb- 1, which is rabbeted at 2 to receive the striking portion of the door when closed. A socket 3 is made in the face .4 ofthe door jamb forv receiving the metal required depth. Thishole is then opened to the rabbeted jedge between horizontal lines that aretangential to the circular hole. i

v -The container 5 ispreferably constructed' ofV sheet metal and is rectangular' in cross L section as shown in Figure 3, havinga bot- ,tomV 6 and vertical sides 7 which terminate at their upper edge into outwardly t'urned Aflanges 8. An end Soffthe `container is circular in--form and is integral with the sides e Zwhich are tangential to the-,circular end.

Y The oppositeendof the container is open A.for the insertion 'of a buffer Vblock .10. At theopen end, the sides .7 havel inturned langesll which. engage outwardly` turned.'v Y lianges 12 ofthe buffer block and limit the Other and further important ob]ects of.

outward Y movement of the block-relative to the container. An aperture 13a is positioned i' at the center ofthe circular portionfof the container bottom, thru which a'screw 13 may f be inserted for'holding the container inthe "walls 7. Opposed depressions 16 are made in theV cover plate, with a spacer'betwe-en their adjacent ends for engaging the top edgeof Y the circula-rv end 9 to prevent the cover from being jarred loose by car vibrations. f A ilat spring is formed into a circle leaving a space between its'ends TheV spring 17 lits into the contain-er as shown vin Figure 2, the portion opposite thev free' ends pushing againstA the buer block and moving it outwardly until the flanges 12 are against the iianges 11.

A modified form of mounting is shown in Figure 5. The container does not have a cover as shown in the preferred form of mounting.V The container 19, Figure .5, is cup-shaped, having inturned flanges -on its bottom face for retaining the ouder-block spring 2l inplace. The spring. 21 is the same as the spring '17 Figurefih The top 'face o y the container has an aperture for receiving thek mounting screw 22 which extendsthru the face into the door j amb 23 Aand holds the buii'er in place in the socket 24which is similar in all respects to the socket' 3 in Figure '4. The'huii'er'hlock 25 is thesame asin the preferred form, having outwardly :turned Eflangesfor engagement with inwardlyturned Vlanges on the end face of the container; L20

In the use of this inventiomff the container is position-ed invv the socket and securedfby the screw 18 to the door `jamh;"the'loufi"er block Illinois.

'BEYNON Y is inserted in theopen end of the container y Y andthe spring placed back of it. The cover plate is then slipped over the front face flanges of the container and secured by the depressed portions of the cover engaging on earch side of the circular 'end wall of the container.' The buffer as thus mounted, will jamb; kIt is, therefore, obvious that when `the door Y18 is closed it will Vcompressthe buffer block, which is made of a resilient material. As the door continues to its fully closed position, the increased `pressure againstfthe b/uii'er blockwill cause it-'to move 4inwardly against the pressure ofthe spring -fec The use/of this invention, therefore, Aprovides a bufferwhich automatically compen-y sates for the wear of the bufferhlock which,

when' desired', may'easily'he replaced hy a new one by simplysliding back the cover plate, thus permitting fthe removal of the oldhlo'ck and the insertion of a new one; without havingto loosen any screws.

-I am aware that manychangesmayfhc made,'and numerous details of construction may be varied through a .wide range without departing rom'the principles of this invenftion, and yI, therefore, do not'purpose limit-'- ing the vp atent granted'hereon, otherwise-than necessitated by theprior'art.
